The Kapuas River is the longest river in Indonesia, stretching approximately 1,143 kilometers across West Kalimantan on the island of Borneo. The river begins in the Müller Mountains and flows westward until it reaches the South China Sea. The Kapuas River is extremely important for local communities because it is used for daily transportation, fishing, trade, and agriculture. Along the riverbanks, many traditional Dayak and Malay villages can be found. The Kapuas River is also rich in biodiversity and is home to rare species such as the Asian arowana (super red fish) and various types of freshwater ecosystems. It is not only a natural treasure of Indonesia, but also a source of life for millions of people in Kalimantan.
